MACHINE FOR THE MANUFACTURE OF CLOTH COVERING- TUBES FOR AUTOMOBILEWINDOW SASH.

Application filed August 12,1920. Serial No. 403,043.

To all whom it may concern:

Be it known that 1, PAUL RISSMANN, a citizen of the United States,residing at Detroit, in the county of Wayne, and State of Michigan, haveinvented certain new and useful Improvements in a Machine for theManufacture of Cloth Covering Tubes for Automobile Window Sash, of whichthe following is a specification.

This invention relates specifically to a machine for forming thecovering for metal channels used to form the sash of an automobileclosed body window.. Of course, the invention is of broader scope thanthe manufacture of the specific material referred to.

The broad invention may be said to be apparatus for making a piece offabric tubing out of material folded upon itself and then securedtogether with an adhesive strip and further in a broad sense thebutt-joining of two pieces of fabric. The particular features of theconstruction will be best understood when a detailed description is hadof the apparatus.

In the drawings,

Fig. 1 is a side elevation of the machine.

Fig. 2 is a plan view of the machine.

Fig. 3 is an end elevation of the same taken from the right of Fig. 1.1B Fig. 4 is a section on the line 44 of ig. -5 is a section on the line5-5 of Fig. 2. FFig. 6 is a section on the line 6-6 of ne of the mostcommon forms of window sash now used for automobile closed bodies is onethat is formed by a metal channel and suitably covered usually with afelt cloth or equivalent fabric material (see patent to John T. AllmandNo. 1,147,837 The present method of fastening this cloth to the channelstrip is to form it into a tube of proper width, whip-stitching ittogether. This forms a tube into which the channel may be slid, togetherwith the packing that has been glued to it (see patent to A. Gagnon No.1,243,728, for description of how the felt packing can be applied). Thispacking is covered with glue or other adhesivebefore bein slid into thefabric tube. A form 7 mem er is then slipped-into the channel siveoperation compared with an automatic operation but the results are notas good for the reason that the stitching cannot possibly be as regularas work done by the apparatus now about to be described.

a designates a bench on which a machine performing. the work outlined isfastened. The machine comprises a base I) attached by bolts 0 to thetable 0:. e is a pulley wheel adapted to be driven by a belt and havinga shaft f journaled in the bearing '9 rising from the base I). The spoolit stores a roll of fabric ribbon while a narrower spool 11 stores aroll of tape impregnated with rubber or some other sticky or glue-likesubstance. This will be called an adhesive tape in the claims. j is aguide arranged to take a cloth or fabric ribbon, double it upon itselfto form a strip or preliminary tube of half the width of the originalfabric, with the meeting edges meeting at the center of the strip. Thisit accomplishes by the ,folded-over converging guide is shown in Fig. 2,and sections of which are shown in Figs. 4 and 5. Suspended above thecloth and supported uponthis guide j, is a centering guide Z for theadhesive tape Z. This centering tape guide m simply rests on the top nof the fabric ribbon guide, being soldered to the reinforcing strip 0soldered to this top. Another centering guide for the adhesive tape isdesignated 19 and is also soldered to the top of the fabric ribbon guidewhere it turns the outside in. This guide may now be properlyappreciated. The fabric is fed ofi from the spool flatwise into thisguide. By examining Fig. 4, it will be seen that the guide almostimmediately begins to turn the edge portions of the ribbon in or concavethe ribbon. The edges of the guide then are completely turned over (theoutside turns in) at is until they meet. A little partition 9 dividesthe turned-over edge portions of the ribbon, while the top 11. (thathasbeen turned from outside in) serves to divide the foldedthat is fedupon the heating roll u. This heating roll u has a hollow interior inwhich is suspended a ring 41 having gas jet orifices which form a burnerfor heating the interior of the heating roll u. This member is suspendedwithin the roll by the pipe .w-

which supplies the mixture for combustion. It will be evident from thisdescription that first the under. side of the preliminarily-preparedfabric tube is heated by being drawn over the concave heating iron 8.This heating is only an indirect or secondary one as on y heat firstused on the heating roll it reaches the concave iron 8. This is all thatis required to warm the preliminarilyformed tube on the under side. Thepreliminarily-formed tube is then reversedby the roll t, and the sidethat has the meeting ed es which are desired to be secured to the ruber-impregnated tape is brought directly over the. relatively higherheated heating roll u. The rubber in the tape is thus caused to melt andsoften. The heating roll then pinches the preliminarily-formed tubebetween itself and the pressure roll m. This forces some of the softenedfluid-like rubber compound into the edge portions of the fabric Wherethey meet, thereby securely fastening the fabric edges to theimpregnated tape and thereby firmly securing them to each other. Thecompleted fabric tubing then passes on to the spool y, completing thesame and making itready for use.

The heating roll is carried on a shaft 2 which is journaled in a yoke orsupport 1.

The pressure roll a: is always fixed and always rotating, being carriedon the end of the pulley shaft f. As soon as the heating roll-u ispressed against the pressure roll a;

it starts the tape, fabric ribbon, and the com- I pleted tube moving inthis way: the heating roll u being pressed against the pressure roll a:that is rotating, is also caused to rotate.

This ulls the reversing roll if from the posi- 7 tion s own in thedotted lines of Fig. 6 over against the heating roll, as shown in fulllines in this figure. The ironing roll then serves to rotate the tapespool and the fabric ribbon spool simply by pulling the material offfrom these two spools. The shaft 2 is journaled'in the yoke 1, which ispivotally supported on the upstanding lugs 2 of the casting which formsthe base b of the machine. Within. the space between the yoke legs islocated a pulley wheel 3 fast to the shaft .2. This, through a belt orcord 4, drives the pulley wheel 5, which in turn drives the storagespool 3 The belt may slip enough to compensate for an otherwisedifferential peripheral speed of the spool y 'as it fills up.

As already indicated, the yoke 1, which journals the heating roll and ispivoted to the base at 6, may be drawn. down to bring the heating rollagainst the "pressure roll :10. The foot of the operator may be broughtagainst the pedal 7 which connects through the draw rod 8 with the yoke9 that has two aI'IIIQS 10 connected with opposite sides of the yo e.

Referring to Fig. 3, it will also be seen that the lugs 11 on the bedcasting support an arm 12 which supports the guide 7'.

One side of the spoolsz' and k may he slipped off at any time to replacethe tape or fabric ribbon by loosening the set screws 13 and 14.

It will be apparent that'in a broader sense the apparatus is a machinefor joining in a butt-seam two pieces of fabric, and hence claims aredirected to this.

What I claim is:

1. A machine for butt-joining fabric portions, comprising a guide havingthe capacity of directing and guiding the edges of the fabric portionsto hold the same in abutting relation and also to guide an adhesive tapealong the meeting edges, a heater, a pressure member, and means fordirecting and pulling the fabric and tape in adjacency to the heater andinto the pressure member, which serves to force the adhesive tape uponthe said adjoining edges of the fabric.

2. A machine for butt-joining fabric portions, having in combination, aguide for directing fabric pieces into abutment at their edges and alsoserving to guide a traveling adhesive tape upon the edge portions abutting,- a heater, a pressure member, and means for pulling the tape andfabric in proximity to theheater and against the pressure member topress the adhesive tape against the edge portions of the. fabric tocomplete the same.

3. A machine for butt-joining fabric portions, having in combination, aguide for directing the edge portions of traveling fabric into abuttingrelation and at the same time guide a traveling adhesive'tape "alongsideof the edge portions, a heating roll,

4. A. machine for butt-joining fabric edges, comprising a guideforfdirecting the edges of traveling fabric to cause them to abut and atthe sametime direct aitraveling adhesive tape alongside of the edges, 8.heating roll journaled in, a movably-hung sup-s port, a pressure rollagainst which the heating roll abuts, and means for drawing the fabricand adhesive. tape over the heating roll and between the heating roll. 35. A machine for butt-joining fabric edges, having in combination,aguide for directing the edge portions of traveling fabric to cause themto abut and also for guiding a' traveling adhesive tape along the edgeportions of fabric, a heating roll journaled in a pivotally-hungsupport, a pressure roll, means by Which the operator may move thepivotal support for the heating roll to press the same against thepressure roll, and means for pullingthe fabric and tape over the heatingroll and between the heating roll and pressure roll.

6. A machine for butt-joining fabric edges, having in combination, aguide for pressure roll and the directing fabric portions to cause theedges to abut and at the same time guiding a traveling adhesive tapealongside of the meeting edges, a heating iron, a heating roll having agreater heat than the first-mentioned heating iron, means for reversingthe traveling fabric and tape that pass from the heating iron to theheating roll, means for pressing the tape and fabric edge portionstogether after having passed over the heating roll, and means forpulling the fabric and tape through the aforementionedinstrumentalities.

' 7 A machine for butt-joining fabric edges, having in combination, aguide for directing traveling fabric to cause the edge portion to meetand at the same time guiding a traveling adhesive tape alongside of theedge portions, and a heating roll and heating iron above the heatingroll, means for heating the ironing roll and giving the heating iron asecondary heat, areversing member for taking the fabric and tape as itleaves the heating iron and reversing the same as it passes on to theheating roll, means for pressing the adhesive tape to the fabric edgeportions as it passes off the heating roll, and means for drawing thetape and fabric through the aforementioned instrumentalities.

' In testimony whereof I affix my signature.

PAUL RISSMANN.
